Getting Started with Python

To begin coding in Python, you'll need to install the Python interpreter and set up your development environment.

1. Downloading and Setting Up Python

First, head over to Python's official website to download the latest version of Python. Select the appropriate version for your operating system (Windows, macOS, or Linux).

2. Python IDLE Installation

Once Python is installed, the Integrated Development and Learning Environment (IDLE) will also be installed. IDLE is a basic IDE that lets you write and run Python code directly.

Interactive Mode vs. Script Mode

Interactive Mode

In interactive mode, you can run Python commands one line at a time. This mode is useful for testing small chunks of code or for learning Python interactively. To open the interactive mode:

• Open your command prompt (Windows) or terminal (macOS/Linux).

• Type python and press Enter. You’ll see a prompt where you can start typing Python commands.

Script Mode

In script mode, you write Python code in a file and execute it all at once. This mode is ideal for writing longer programs. To use script mode:

• Open IDLE.

• Write your code in the editor.

• Save the file with a .py extension.

• Run the code by pressing F5 or selecting Run > Run Module from the menu.

Python Statements and Comments

Python Statements

In Python, a statement is a line of code that performs a specific action. For example:

print("Hello, World!")

This statement prints the text "Hello, World!" to the screen.

Python Comments

Comments are lines in the code that are ignored by Python but are useful for explaining what your code does. Comments start with a # symbol:

# This is a comment
